How to burn calories without sweating??
How good do you have to speak in order to become the President of United States?
Well first of all, you need to be able to speak to your audience without any written script in front of you, and at the same time, be confident. In none of Obama's speeches that I have seen has he looked at any script before. Either he is really a good public speaker, or that he has memorized his prepared speech, usually goes up to an hour, word-by-word.
Secondly, you need to be able to contain yourself from being frustrated of all the interruptions that you'll get when you speak. In Obama's 52-minute speech to the Congress last night, he had to stop, in between his sentences, for 65 applauses and 32 standing ovations!
